HINGE.

Application filed June 27, 1922. Serial No. 571,194.

This invention relates to awning frame hinges and particularly to thattype which enables the sides of the awning frame to be folded fiat onthe front or main portion of the awning.

The primary object of my invention is the provision of an improved hingefor awning frames which will permit of the folding of the sides theframe in parallel relation to the front or main portion of the frame.

Another object of my invention is the provision of a hinge for an awningframe which when installed in a fold of the flexible body portion willnot catch, tear or cut the flexible body portion when the bending at thehinges takes place and will at all times, whether bent or straight,present smooth surfaces to the flexible body portion.

Referring to the drawing where preferred embodiments of my invention areillusl' 'ated,

Figure 1 illustrates an awning with my improved hinge installed therein,a portion being broken away to show its application.

Figure 2 is a view similar to Figure 1 but showing the awning folded.

Figure 3 illustrates a plan view of one of my improved hinges when inopen position.

Figure 4 is a view similar to Figure 3 but showing the hinge in closedposition.

Figure 5 illustrates a cross section on the line 55 of Figure 3.

Figure 6 illustrates a modified form of my invention.

Figure 7 illustrates a further modification of my improved hinge.

Figure 8 is a cross section taken on the line 8-8 of Fig.6.

Like reference characters refer to similar parts throughout the severalviews.

10 designates a window to which the awning frame may be fastened, 11 theroller upon which the awning may be rolled. The awning body 12 isattached to the awning frame 13 with a fold l t at its lower edge whichencloses the frame.

The hinges which secure the parts of the frame together are of the rulejoint type. A hinge member is here shown as provided with a rightangular portion bearing a threaded end 21 and two jaws 22 which receivethe tongue 23 of the other hinge portion 24. A threaded end is providedon the end of the hinge portion 24. The members 20 and 24 are providedwith shoulders 26, 27, respectively, and complementary to each other.When the hinge is open as shown in Fig. 3, the axes of the portions 21and 25 being at about 87, the shoulders 26, 27 are in contact. When thehinge is closed as shown in Fig. 4, the shoulders are out of contact.The edges of the pairs 22 are chamfered as shown in Fig. 8, so that whenthe hinge is closed as in Fig. i, there will be no sharp edges tocontact with the body portion of the awning. A pin 28 hinges the parts20, 2a together.

In Figure 6, the hinge members 20, 24 have internally threaded portions21, 25', respectively. The parts 22, 23, 26, 27', 28 correspond,respectively, with the parts 23, 26, 27, 28 of Figs. 8 and 4.

In Figure 7, I have illustrated the hinge members 20, 24: held togetherwith the pin 28".

My invention is particularly adapted for use with rods and pipes ortubes, thereby making the use of tools, other than ordinary pipe tools,unnecessary.

This inventon although described in connection with an awning is equallyadapted.

for use in ventilators, folding beds and other similar places wherefolding frames are used.

While I have described embodiments of my invention in detail, I desireto have it understood that I do not limit myself to the exact structureshown and that modifications and changes may be made without departingfrom the spirit of my invention and within the scope of the appendedclaim.

Having described my invention, what I claim is A hinge comprising a bodymember having two jaws and being of substantially circular cross.section, another body member havinga tongue and of similar crosssection, the tongue being pivoted between the jaws, means at the end ofthe body members for attachment to a pipe or rod, one of the bodymembers having a substantially right angular turn therein, the outerportion of the aws conforming substantially to the contours of the bodyportions and presenting curved surfaces in all positions.

In testimony whereof I hereunto affix my signature.

GEORGE S. HENRITZY.
